SPECIFICATION forming part of Letters Patent No. 782,591, datedFebruary. 14, 1905.

Application filed September 23, 1904. Serial No. 225,602. v

To It whom it may concern: I 7 Be it known that I, PERCY H. BATTEN, ofChicago, inthe county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Power Installation forSelf-Propelled Vehicles; and I hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, which form part of this specification. v I

My invention relates to improvements in power installations forself-propelled vehicles,

and is applicable to automobiles, street-cars,

railways, and the like.

In the drawings, Figure 1 is a plan view of the frame and running-gearof a street-car equipped with a power installation embody- 1ng myinvention; Fig.2is a fragmentary longitudinalsection on line 2 2 of Fig.1, and Fig. 3 is a transverse vertical section online 3 3 of Fig. 1. 5

Throughout the drawings like numerals of reference refer always to likeparts:

10 indicates in general the frame of a selfpropelled vehicle, having atits opposite ends bearings 11 11 and 11 11' for two axles 12 12', uponwhich are mounted the pairs of tractionwheels '13 13 and 13 13.

14 indicates in general a prime motor, preferably an explosive-engine,supported ons'uitable frame members 15 15 and preferably disposed towardone side of the frame 10, between the axles 12 12', about midway of theframe.

16 indicates the engine-shaft, preferably extending longitudinally ofthe frame and journaled in suitable bearings 17 '17. On the engine-shaftI arrange means for providing two friction-surfaces facing in oppositedirections, such surfaces being preferably supplied by twooutwardly-facing disks 18 18, fixed on opposite ends of the shaft 16 andarranged transversely of the frame.

19 indicates a driven disk arranged in edgeto-face relation to thedriving disk 18 and splined on a transverse shaft 20 to slidelongitudinally thereof and to rotate therewith. The shaft 20 is mountedfor bodily movement transversely of its length toward and from the faceof the driving-disk l8, and to this end .the opposite ends of the shaftare-mounted in rocking frames 21 21, pivoted upon a shaft 22, extendingtransversely of the car and suit' ably supported, as in brackets 23,said frames 21 having each a horizontal extension 24, which 1 serves asa lever--. arm to move the frame.

such means being herein illustrated as a longitudinal rock-shaft 25,extending from end to end of the car, and at its end, at some suit ablepoint. provided with a crank-arm 26,with

which engages the treadle-lever 27, extending into suitable position foroperation by the driver of the car.

28 indicates a cable secured to the shaft 25,

having two branches 29 29 running over suitable idlers 30 30 and securedto the extremities of the lever-arms 24 24. The arrangement of the partsis such that when the treadlelever 27 is depressed-andthe rock-shaft 25rocked the rocking frame 21 is oscillated to I dle-lever 27. v

Aspring31 is provided in association with each of the lever-arms 24 ofthe rocking framesjftending to throw said frames in thereversedirection, so that as soon as pressure is removed from the lever27 the driven disk is thrown out of engagement with the drivingdisk. i

Parts similar. to those described are pro- This condition prevails-aslong as pressure is maintained upon the trea vided in conjunctionwithdisk 18' and are associated, as by miter-gears 33, with the 0011-trolling-crank 34, arranged for operation by the driver of the car. Theshaft 33 is provided with a pinion 35, with which meshes a rack 36,extending transversely of the car and having a fork 37 engaging with thegrooved collar 38 of the driven disk 19. It will be apparent that byrotary motion of the lever 34: rotation is imparted to the shaft 32, andthrough the agency of the pinion 35 and the rack-bar 36 the driven diskis slid transversely of the face of the driving-disk.

The shaft 20 is operatively associated with one of the vehicle-wheels 13to positively drive the same, and to this end I provide a tumble-shaftat one end supported in a hearing 40 for slight movement in anydirection and at its opposite end connected by a universal joint ll withthe shaft 20. The tumble-shaft 39 carries a pinion .42, which mesheswith the gear 13, carried by the axle 12 of the wheel 13.

The arrangement of parts at the other end of the car-that is to say, theassociation of parts with the driven disk 19is identical with that just,described, like parts being indicated throughout by like numerals ofreference differentiated by the exponent character prime It is to benoted, however, that while the disk 19 is on one side of the axis ofrotation of the driving-disk the driven disk 19' is upon the oppositeside of its coacting driver, and it is further to be noted that whilethe rack-bar 36 of the disk 18 passes over its pinion 35 the rack-bar36' of the driven disk 19 passes under its pinion 35, so that themovement of the disks 19 19 will be in opposite directions with respectto each other, but in like radial direction relative to their respectivedriving-disks. The connections of the driven disks with thetraction-wheels of theilr respective ends of the vehicle are identica Itwill now be apparent that when the parts are in motion, assuming thedirection of rotation of the driving-disk 18 18 to be that indicated bythe arrows,the coacting rotary members will rotate in the directionsindicated, respectively, by the arrows and both drivingwheels 13 and 13'be driven in like direction. The speed may be changed or the directionof progression reversed by operation of the controlling-lever 34: toshift the driven disks 19 19' transversely of their driving-disks, asheretofore described, and power may be applied to or released from thedriving-wheels 13 13 by the manipulation of the treadle-lever 27, alsoas heretofore described.

While I have herein described in some detail an operative embodiment ofmy invention, I do not desire to be understood as limiting myself to thespecific construction shown and described, as such construction isillustrative merely, and it will be apparent to those skilled in the artthat numerous changes might be made in the specific embodiment of myinvention without departing from its spirit and scope.

gear, comprising two independent tractionwheels, of an engine having ashaft,means on the engine-shaft providing two driving-surfaces, a drivendisk arranged for edge-to-face contact with each driving-surface, andmovable on a diametrical line across the axis of the driving-surface,means for so moving each driven disk, and operative connections betweenthe driven disks and the respective traction-wheels.v

2. The combination with a vehicle runninggear, comprising twoindependent tractionwheels, of an engine having a shaft, a drivingdiskon each end of the. engine-shaft, a driven disk for each driving-disk,the driven disks being disposed on opposite sides of the shaftaxis andarranged for edge-to-face contact with opposite faces of the driving-disks, each driven disk being movable diametrically across the axis ofits driving-disk, and like connections as to direction of rotationbetween the two driven disks and the respective traction-wheels. l

3. The combination with a vehicle runninggear, comprising twoindependent wheels at opposite ends of the vehicle, of an engine mountedbetween the front and rear wheels, a driving-disk on each end of theengine-shaft, a driven disk in edge-tdface relation to eachdriving-disk, the two driven disks being arranged on opposite sides ofthe axis of the driving-disks, means for simultaneously moving thedriven disks in opposite directions across the faces of thedriving-disks, and like connections between the two driven disks and therespective traction-wheels.

'4. In combination with a vehicle runninggear, comprising twoindependent drivingwheels at opposite ends of the vehicle, an enginemounted between the front and rear wheels, a driving-disk on each end ofthe engine-shaft, a drivendisk in edge-to-face relation to eachdriving-disk, a shaft for each driven disk movable toward and from thesurface of the driving-disk, a tumble-shaft connected with each drivendisk-shaft, and like connections between the tumble-shafts and theirrespective traction-wheels.

5. In combination, a bodily-stationary friction disk, a bodily movablefriction disk adapted to coact therewith, and means for supporting andmoving said friction-disk comprising a rocking frame carrying themovable disk, a rotatable shaft, a cable associated with said shaft tobe pulled by the rotation thereof, and connected with the rocking framein one direction and means for movingsaid frame in the oppositedirection.

In testimony that I claim the foregoing as my own I-afiix my signaturein presence of two witnesses. I
